Palo Verde Dam
The Palo Verde Dam (officially called the Palo Verde Diversion Dam) is a diversion dam on the Colorado River in La Paz County, Arizona, and Riverside County, California, in the southwestern United States, approximately northeast of Blythe. The dam is earthen and rockfill, built solely to divert water into irrigation canals serving the Palo Verde Irrigation District. It measures long at its crest, which is at an elevation of , and stands high above the riverbed, containing approximately of material. Construction of the dam, which began in 1956 and ended in 1958, was authorized by the U.S. Bureau of Reclamation. The dam was constructed to raise the water level of the river because the upstream Hoover and Davis Dams blocked sediment, causing significant degradation of the riverbed that hampered water diversion.〔(【引用サイトリンク】title=U.S. Bureau of Reclamation- Palo Verde Dam ) 〕
The dam diverts about of water per second to irrigate of the Palo Verde Valley and mesa lands on the west side of the Colorado River in California. The headworks of the diversion canal consists of four by pipes, while the spillway is a gated structure consisting of three long gates separated by thick piers. The control house of the dam is found immediately upstream of the headworks area.〔
